ABSTRACT:
A reinforced high viscosity rubber composition having improved processability such as reduced mixing cycles contains large sized particles of carbon black. The carbon black has low structure and a low DBP absorption number as well as a low iodine number. The rubber composition is useful in various tire rubber compositions such as those requiring a high viscosity, for example an apex rubber.
